Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing mechanism for a lid attached to a storage opening of a console box, a glove box, or the like provided in, for example, an automobile. The present invention relates to a lid opening / closing mechanism for a vehicle storage compartment having a structure that can be opened to a predetermined position and thereafter can be stopped at an appropriate position by manual force.

[0002]

2. Description of the Related Art Generally, an opening of a storage box such as a console box or a glove box installed in a vehicle interior of an automobile is covered with a lid so as to be openable and closable. As described above, the lid body structure provided for opening and closing the horizontal opening is supported at one side end so as to be openable and closable via a hinge, and always utilizes the weight of the lid body. The opening of the console box is closed.

When the user wants to open the lid, a mechanism for opening and closing the lid can maintain the fully opened state by rotating the lid by about 90 degrees or more with manual force. It is well known.

[0004]

However, in such a conventional lid opening / closing mechanism, the lid is moved about 90 degrees from the closed position.
The lid could not be stopped at an intermediate position between the open positions, and the opening of the lid could not be freely determined.

[0005] Therefore, in order to freely determine the opening degree of the lid, a frictional resistance against the weight of the lid is applied to the lid at all of its open positions. Although an opening / closing mechanism is also known, even with such a lid opening / closing mechanism, the power for opening the lid relies on manual force, and the opening operability of the lid is lacking.

The present invention has been made in view of the above. When the lock mechanism that holds the lid in a closed state is released, the lid moves to a predetermined position from the closed state of the container opening. The lid is automatically opened without manual operation, and within the opening movement range from the predetermined open position to the fully opened position of the lid, the lid can be stopped at any position by manual force, and the lid can be stopped. The object of the present invention is to enhance the operability of opening the lid, especially at the beginning of opening.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a lid for closing an opening provided in a container main body so that the opening can be opened and closed. A fixed bearing is fixed to a side edge, and a movable bearing is fixed to one side of the lid, and the fixed bearing and the movable bearing can be turned via a pivot bolt. In a lid opening / closing mechanism for a vault for a vehicle, further comprising a lock mechanism for preventing the lid from being opened at the other side edge of the lid, the lid may be provided in accordance with the opening angle of the lid. A spring member that applies an opening torque that is inversely proportional, and a friction torque applying member that applies a substantially constant friction torque to the lid regardless of the opening angle thereof are provided, and the opening angle of the lid is a predetermined opening from a closed state. Between the angular positions, the opening torque by the spring member Is set to be higher than the friction torque by the friction torque applying member, and when the opening angle of the lid is between the predetermined opening angle position and the fully opened state, the friction torque by the friction torque applying member is increased by the spring member. The opening / closing mechanism of the vehicle storage compartment is set to exceed the opening torque of the vehicle.

According to the first aspect of the present invention, the initial opening of the lid for opening and closing the opening of the container main body can be easily and quickly performed by using the opening torque of the spring member. The lid, which has been initially opened, can be opened to an arbitrary opening angle by the occupant performing the opening operation against the friction torque, and the lid stops at that position if the release operation is released. In addition, it is possible to provide a lid opening / closing mechanism having excellent opening operability.

According to a second aspect of the present invention, in addition to the first aspect, the spring member is inserted into the support shaft bolt, one end of the spring member is engaged with the fixed bearing, and the other end is movable. The friction torque applying member comprises a washer which is inserted into the spindle bolt and generates a friction torque between the fixed bearing and the movable bearing. It is a lid opening and closing mechanism for a vehicle storage.

According to the second aspect of the present invention, the spring member and the friction torque applying member can be integrated around the support bolt, so that the lid of the vehicle storage compartment can be compact. A body opening and closing mechanism can be provided.

According to a third aspect of the present invention, in addition to the second aspect, the coil spring is a lid opening / closing mechanism for a vehicle storage compartment which is inserted into the spindle bolt via a resin spacer tube. It is characterized by being.

According to the third aspect of the present invention, a smooth operation of the coil spring can be ensured by the spacer tube, and the spacer tube is made of resin. It is possible to reduce abnormal noise caused by contact between the coil spring and the spacer tube due to vibration or the like.
